FIELD: analytical chemistry of organic compounds. SUBSTANCE: process is meant for selective determination of butylacetate as key component of gas effluents of furniture factory at level of 1/2 maximum permissible concentration. Piezoquartz resonators of matrix are modified by sorbents: bee glue, beeswax, polyehtyleneglycol succinate, triton X-100, polysterene, polyethyleneglycol PEG-200 in certain mass range, individual for each sorbent. EFFECT: reduced detection threshold, decreased time of analysis and enhanced determination accuracy. 6 dwg, 1 tbl |
